Its usually good to get a higher amperage skateboard for more power going off road or up steep hills. But the more amperage the motor draws the faster the battery is used up. The extremes are the 20 amp GnawBoard and the 7 amp Pipemaster. The Pipemaster has the least torque but the longest run time but still gets to 22 miles per hour on flats with its maximum weight limit.
The higher amperage models don't run anywhere near mileage like the Pipemaster but people usually have to make a choice if they want power and super torque or high run times and longer to get to top speed. The heavier boards are harder to turn a sharper radius turn than the 17 lb boards that have short turning radiuses.
There are boards with the same wattage but different amperages. You can have two similar watt board but one can have 10 amps, the other 18 amps, and the other only 12 amps.
If you want higher run time, you can go with lower amps but if you want power and super fast acceleration and high torque, many people go with higher amps. If you really want power even go with a brushed motor but many people don't like them because they don't run as long but when I want to go fast to race a bike up a hill, I wish I had the brushed motor.
What you notice in higher amperage is instead of a gently pushing you forward, you feel the G force in your feet and you have to use your core muscles to keep your body straight to hold on and if the board has a raised edge on the ends, you might not be able to hold on without them.
For lightweight people, a lower amperage model can be suitable. If someone is about 180 lbs and they want to feel that G force behind the acceleration, then 12 amps or more is what it will probably take. The 7 amp models can get a person to the same speed on flat ground but it just takes a little longer to build up speed. But then again this saves battery life and gives about 5 extra miles. If you don't care about the extra run time, I personally have much more fun on a more powerful board. But just for going to the store and back, I take my light board with me when I'm not really want or need extra power.
Bottom line: Getting a more higher amperage power motor is better especially when heavy loads are on it. Higher amperage boards are more expensive but as long as the battery is good. Some batteries give power to give lots of G force or the first part of the battery life but the other portion of the time I'm on it that initial G force it had is diminished. Make sure your batteries are strong enough to power the board and give the performance almost the whole time. Cheap batteries loose it. Its like my RC car that goes around 100 mph. The first 5 minutes is all I use each battery for although it can go for about 22 minutes. I have 4 batteries and once I see that the power is not the same as a fresh charged battery, I just switch it out. This is how I feel when I use cheaper batteries.
There are a lot of skateboards claiming high amperage. There are only a few that have the battery supply to back the board up for the G force I want. Take my quiz and I will help you pick out a board with the right battery supply and amperage based on the answers you select.
